An object including a first puzzle piece comprising:
- a body having a first outer side edge and a second outer side edge;
- a plurality of joints positioned along the first and second outer side edges, each joint having a substantially U-shaped mortise defined by a first side wall, a second side wall, and a straight bottom edge that connects the first and second side walls, with the bottom edge of at least one joint having a width which is different from the width of the bottom edge of the other joints;
- and
- wherein the first puzzle piece comprises a corner connecting the first and second outer side edges, and a corner joint provided at the corner, the corner joint having a substantially U-shaped mortise defined by a first side wall, a second side wall and a bottom edge, with the first side wall of the corner joint extending from the bottom edge to the first outer side edge, and the second side wall of the corner joint extending from the bottom edge to the second outer side edge.
